streams, about three miles out from Tumatumari, was fol- 

 lowed to its mouth in Tiger Creek. Collected February 5-13, 

 1912. 



Hetaerinas Avere rare about Tumatumari, the total capture 

 amounting to only sixty-seven specimens, thirty-six of which 

 were dominnla. On Cashew Creek we took dominula and 

 moribunda, each represented by two specimens, and mortua, 

 represented by a single specimen. On the first small creek 

 out from town on the Tiger Creek trail we collected four 

 specimens of dominula, and on the creek on the left bank of 

 the river, below the falls, we found domnida, laesa, moribunda 

 and iiiortiM, the first represented in the collection by thirty 

 specimens, the next two by one specimen each, and the last, 

 mortua^ by twenty-six specimens. 



51. Wismar, on the Demerara River, sixty-two miles above 

 Georgetown, British Guiana. Elevation not noted. Some 

 small, muddy creeks tributary to the Demerara adjacent to 

 town, easily waded earlier in the day, are so backed up with 

 water in the late afternoon, due to the tides, that the collector 

 finds them impossible to work. There is a small wooded creek 

 south of town and a smaller swamp one, rising in some low 

 hills, just west of town. Below town the footpath to Chris- 

 tianburg crosses a muddy, log-filled creek. At Christianburg 

 there is a small, muddy creek in the brush parallel to and near 

 the left bank of the canal. Collected January 30 and 31 and 

 February 15 and 16, 1912. 



Only two specimens of He\taerina moribunda were taken 

 at Wismar, and our notes are not clear as to exact location. 

 They were taken either on the small creek south of town, or, 

 less probably, on the smaller creek west of town. Dominula, 

 on the other hand, was common and was taken on both the 

 streams mentioned in the preceding sentence and on the stream 

 along the canal at Christianburg.
